GRATE-MOUNTING FOR STOVES OR RANGES.

SPECIFICATION forming part of Letters Patent N 0. 651 ,592, dated June 12, 1900. Application filed October 23, 1899. Serial No. 734,430. (No model.)

To aZZ whom it may concern.-

Be it known that I, VALTER A. CLARK, of the village of Geneva, county of Ontario, and State of New York, have invented new and useful Improvements in Grate-Monti tings for Stoves or Ranges, of which the following is a specification.

Myinvention relates to improvements upon the construction and form of the mountings IO by which grates are connected to and detached from the fire-chambers of stoves and ranges; and these improvements have for their object the formation and arrangement of the mountings in such a manner that the grate can be do- I 5 tached from and connected to the range without the employment of skilled workmen.

Accompanying this specification to form a part of it there are three plates of drawings, containing seven figures, illustrating the apzo plication of my invention,with the same designation of parts by letter reference used in all of them. I

Of the illustrations, Figure 1 is a frontelevation of that part of a cooking-range wherein 2 5 the fire-chamber and ash-pit are located, with the door of the fire-chamber at the front shown as removed. Fig. 2 is a section taken on the line at 00 of Fig. 1, with the illustration shown as broken apart centrally. Fig. 3 is a section taken on the line x on of Fig. 2 through the fire-chamber sides, the slideway made for the grate-frame, and part of the latter, with the grate-sections omitted and the inner end of the grate-frame shown in elevation. Fig. -t is a section taken on the line 00 x of Fig. 6, with the grate-sections indicated by dotted lines. Fig. 5 is a perspective of the grateframe with the grate-retaining plate in position and with the grate-sections omitted. Fig. 6 is another perspective of the grate-frame with the grate-sections indicated by dotted lines, with the grate-retaining plate and the segmental gears by which the grate-sections are operated omitted. Fig. 7 is a perspective of the grate-retaining plate shown as detached.

The several parts of the range thus illustrated and also the parts containing my invention are designated by letter reference, and the function of the parts is described as follows.

The letter T designates the pot-hole top of t the range, to which'my invention is shown as applied.

The letter F designates its front, B the back, and E that end of the range which is next adjacent to the fire-chainberf The letter A designates the ash-pit, located beneath the fire-chamber, and the letter F designates the grateframe, having at each of its sides the laterally-projected andoutwardlyextended edge Z, and the letters S designate a ledge or shelf, of which there is one at each side of the ash-chamber, projected inwardly therefrom, and thus forming the slideway to at each side of the ash-pit, wherein one of the edges Z of each of the grate-frame sides may be entered and by which the grate-frame may be slid in under the fire-chamber or drawn out therefrom.

The grate-frame F has the front depend- 7o ing end 6' and the rear depending end 6 I The letters G designate the grate, composed of the grate-sections g 9. Each of these grate-sections at its rear end is provided with a journal end J and at its front end with a journal end J The rear end 6 of the grate-frame is provided with two journal-bearings formed in its inner vertical face f said bearings being designated at 1) b each of which latter is by its construction and location adapted to receive one of the journals J of one of the grate-sections, and the front end of the grate-frame F is cut away from its top downwardly and inwardly and is provided with a semicircular bearing part b in its upper surface at each side of the upwardly-projected central part 19 into each of which semicircular bearing parts the journal J of one of the grate-sections journals.

Each of the inner sides of the cut-away area a of the front end 6 of the grate-frame is grooved or recessed at (E, and the letter P designates a grate-retaining plate, which at each of its outer end edges is ribbed at R and 95 on its bottom edge is constructed with the semicircular cap-bearing parts 5 of which there is one at each side of the centrally-located recess R As thus constructed when the grate-sections are in place within the ICC grate-frame, with the journal J of each of them within one of the bearings b in the rear end plate of the grate-frame, and the journal J of each of the grate-sections is resting in one of the semicircular bearing parts 11 of the end plate 9' and the plate P is passed downwardly to enter the cut-away area of the front end plate, with the rib R at each side of the plate P entering one of the groovesor recesses a of the grate-frame front end plate, and the projection P of the latter entering the recess of the plate P, and the semicircular bearing parts 19 each combining with one of the semicircular bearing parts 12 to form a bearing for each of the journal parts J and the grate-frame is moved inwardly,with its side edges sliding in the slideways to 20 until the frame is entered, so as to have the frame F with the grate-retaining plate, beneath the supporting-plate M of the fire-brick at the front end of the fire-pot, the grate is firmly and securely held in place. When it is desired to put in a new grate, the frame is drawn out, the plate P removed, the old grate removed and a new one inserted, and the frame moved into position, as before described.

The grate-sections g and g are together operated to oscillate on their journals by means of the segmental gears g 9 each of which is arranged upon one of the journals J at the front end of the latter where projecting beyond the end plate 2 of the grateframe F, with the geared segments arranged to mesh into each other for connected movement.

As the bestmade grates of stoves and ranges are liable to become warped or burned by use, it is a matter of great convenience to a householder to be able to replace a grate which has become defective by use without requiring the services of a stove-mounter to do it. \Vhere my'improved construction of grate'frame and its connections are applied to a range, a new grate may be easily inserted in place of a defective one removed and by a very simple effort.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is-

1. In a stove-grate the combination of a grate-frame adapted to be removably inserted beneath the fire-chamber, composed of two parallel, horizontal side bars, connected at their rear ends, a U-shaped depending cross-piece connecting their front ends, an upward projection in the center of said crosspiece, a plate adapted to fit into said U- shaped cross-piece and onto said projection and to come flush with the top and front end of said grate-frame, a plate depending from the rear end of said grate-frame, and gratesections journaled at their ends in said crosspiece and depending rear plate, substantially as set forth.

2. In a stove-grate, a grate-frame F composed of two parallel side bars connected at the rear, adapted to be removably inserted under the fire'chamber and having its front ends connected by a depending U-shaped cross-piece c, said cross-piece being provided with a central upward projection 19 thus forming two half-bearings b on each side of the same, and grooves (t on the inner side of each arm of said cross-piece c, said grateframe being also provided with a depending plate 6 atthe rear having bearings b in it corresponding to said bearings b, in combination with a plate I having a central recess R in its bottom adapted to fit on said projection p ribs R on each side adapted to fit in said grooves a and recesses b on each side of said recess R adapted to come di rectly above said half-bearings U when the plate I is in position and thus form the upper halves'of said bearings, grate-sections g provided with journals J, J at their ends adapted to be mounted in bearings b D re spectively, and segmental gears g mounted on the front ends of said gratesections and meshing together, substantially as set forth.

Signed at the village of Geneva, Ontario county, State of New York, in the presence of the two witnesses whose names arehereto written, this 28th day of April, 1809.
